Electrochemical and spectroelectrochemical methods were employed to investigate its properties of band energetics and the trap state at different pH values. The flat band edges greatly depended on the pH value of electrolyte, and the flat band edges were -0.70, -0.92 and -1.20 V vs saturated Ag/AgCl at the pH value of 3.0, 6.8 and 13.0, respectively. The results showed that trap state densities also highly depended on pH. The total trap state densities were 3.73 × 1015, 4.02 × 1015 and 6.48 × 1016 cm-2 at pH value of 3.0, 6.8 and 13.0 respectively with maximum located at -0.36 V, -0.50 V and -0.80 V. The results obtained from CVs were in good agreement with that obtained from the measurements of time resolved currents. The size of the peak potentials in the cyclic voltammograms experiments was increased dramatically with the pH value increasing, indicating that traps were surface-related.展开更多

Dietary interventions with naturalproducts have shown promise in preventing and treating NAFLD. Sulforaphane (SFN) is a phytocompoundwith antioxidant and anti-inflammatory properties, and previous research has demonstrated that SFN canameliorate hepatic lipid accumulation and inflammation. However, the molecular mechanisms underlying thesebeneficial effects remain unclear. In this study, we confirmed the protective effects of SFN on excessive lipidaccumulation and inflammatory injury in a high-fat, high-fructose diet-induced non-alcoholic steatohepatitis(NASH) mouse model. We found that SFN attenuates the inflammatory injury in a macrophage cell line andthe liver of NASH mice, owing to the promotion of M1-type macrophage polarization toward the M2-type andthe regulation of inflammatory mediators. Further analysis demonstrated that this SFN-induced macrophageM2-type polarization occurs in a Krüppel-like factor 4 (KLF4)-dependent manner. In summary, we uncovereda new mechanism of action underlying SFN activity and provide evidence that dietary intervention with SFNmight be protective against NASH.展开更多

It also interprets the patents for invention in China from time,research field,and types of applicants. Based on the study,it shows that although the patent applications fluctuate,the general trend is rising. And the patents are mostly concentrated in plant protection,and agricultural biotechnology. The Chinese applicants of patents for invention largely work in the research institutes,and most of these patents focus on the field of plant protection,agricultural biotechnology,and agro-processing.However,the foreign applicants mainly work in companies,and most of these patents only focus on plant protection. These findings will provide a reference for formulating development policies about natural rubber industry in China.展开更多

The mixing patterns and rates are investigated for a binary mixture, represented by two different colors, under several loading profiles. The baffle effectively enhances the convective mixing both in the axial and radial directions, because of the disturbance it causes to the initial flowing layer and solid-body zone, compared with a blender without a baffle. The axial mixing rate is affected by the gap between the baffle and the wall on the left and right sides, and an optimal blade length corresponds to the maximum mixing rate. However, the radial mixing rate increases with the blade length almost monotonically.展开更多
